ok thanks for taking the time to explain to me, it looks like this is the way to go to get the current antenna with RB to put up on the roof, im going to put the antenna in a 3mm diameter rod, upside down, and ubolt it up to the tv antenna, i will then tape the antenna with self amalgamating tape to waterproof it,
i will buy a usb extender, plug the usb local unit into the pc, run a cat5 cable from the usb local unit to the remote unit and then the RB cable back into the remote unit
like pic below
so will this mean i can have the antenna outdoors? will placing it in a 3 - 4 mm aluminium tube interfere with the antenna?
